.SYNOPSIS...

the southern part of the lake. Heavy freezing spray is expected
all of Lake Michigan today into Sunday morning.

High pressure of 30.7 inches will move across Ontario later

scattered snow showers Sunday into Monday. South winds will
increase on Monday into Tuesday, ahead the next low of 29.6 inches
approaching the region.
